Another thought came to mind about the Derp Gun:* It doesn't look that much like a gun. It kinda sorta looks like a pepper spray (or other gas) projector. And that might get people shot.
One of the good things about a traditional gun is that it looks like a gun. The bad guy who you've had to draw on knows that you have a gun and it's pointed at him. A lot of bad guys have a deep-seated aversion to contracting a sudden case of bullet wounds, which is why confrontations often end with the miscreant beating feet.
If, on the other hand, the bad guy doesn't recognize your gun as a gun, you might end up having to shoot him. Which, for you, isn't exactly a good outcome (though better than what it could be). Better for you if he runs away.**

* Writing three posts about a gun that is a toolroom prototype might seem a bit much, I suppose. But a term such as "Derp Gun". is too much fun not to use.
** If he shits his pants and screams, even better.
